  • On the role of performance interference in consolidated environments 

    Rameshan, Navaneeth (Universitat Politècnica de Catalunya, 2016-10-24)
    Doctoral thesis
    Open Access
    Covenantee:  Kungliga Tekniska högskolan
    With the advent of resource shared environments such as the Cloud, virtualization has become the de facto standard for server consolidation. While consolidation improves utilization, it causes performance-interference ...
  • Profiling memory vulnerability of big-data applications 

    Rameshan, Navaneeth; Birke, R.; Navarro Moldes, Leandro; Vlassov, Vladimir; Urgaonkar, B.; Kesidis, G.; Schmatz, M.; Chen, L. Y. (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Restricted access - publisher's policy
    Motivated by the increasing popularity of hosting in-memory big-data analytics in cloud, we present a profiling methodology that can understand how different memory subsystems, i.e., cache and memory bandwidth, are susceptible ...
  • Resource-aware scaling of multi-threaded Java applications in multi-tenancy scenarios 

    Shardomin Simao, Jose Pedro; Rameshan, Navaneeth; Veiga, Luis (IEEE Computer Society Publications, 2013)
    Conference report
    Restricted access - publisher's policy
    Cloud platforms are becoming more prevalent in every computational domain, particularly in e-Science. A typical scientific workload will have a long execution time or be data intensive. Providing an execution environment ...
  • Stay-Away, protecting sensitive applications from performance interference 

    Rameshan, Navaneeth; Navarro Moldes, Leandro; Monte Moreno, Enrique; Vlassov, Vladimir (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    While co-locating virtual machines improves utilization in resource shared environments, the resulting performance interference between VMs is difficult to model or predict. QoS sensitive applications can suffer from ...
